Very impressive job, I must add. Cost wise? Not that bad at all.
I must add that cars in your area are much more intact then up (north) here. The only dilemma I have is this. Do you prime it right away, or weld all the panels in place and then primer the car? ItÃ¢â‚¬â„¢s sort of a catch 22 scenario. If you prime the car right away, it will protect the metal from further rust but it is not fun or good for you, trying to weld things together with primer smouldering in your face. Not to mention your welds will be of poor quality due to contamination. If you wait until all the welding is done then the car is exposed to the unwanted environment and the rust will set in. I think if my body (car that is) was intact, I wouldnÃ¢â‚¬â„¢t think twice about having it acid dipped. In my opinion, money well spent.
